I was diagnosed with sarc after losing my spleen earlier this year to what the drs thought was lymphoma. I also have some lung and liver invlovement ( slighly raised liver enzymes and swollen lymph nodes and some lung scarring, but fortunately, I remain largely asymptomatic and well. If you want to find out more about the causes of sarcoidosis, go to the website www.sarcInfo.com and you will get more information about disease than anywhere else. I have not been able to find a dr willing to try the protocol on the site, as drs only seem to know about prednisone for autoimmune diseases, but I am trying to find a willing and enlightend physician. In the iterim, I am under the care of a homeopathic dr and am doing very well on a diet and many supplements to balance the immune system. Sarcoidosis can go into long or short remissions, but once the bacteria is in your body, it is likely there for life, and you will need regular medical checkups always. I wish everyone here well and continue questioning your drs and forcing them to learn more about a disease many of them know very little about.
